Specification of Letters Patent.

Application filed {uly 9, 1912. Serial No. 708,440.

To all whom it may concern:

Be it known that I, JOHN E. KILBURN, a citizen of the United States, residing at Philadelphia, in the county of Philadelphia and State of; Pennsylvania, have invented certain new and useful Improvements in Pedestals, of which the following is a spoolfication. r

This invention relates to pedestals and has reference particularly to pedestals adapted for use in supporting car-seats. Such pedestals are commonly made of sheet-metal and consist, of a base, usually of oval cross-section, and arms extending forwardly and rearwardly from the upper end of the base and supporting the seat structure. Such a pedestal may be used for supporting the aisle end of a car-seat and the support of the wall end of the seat may be secured to the car wall; if desired, however, two of the pedestals may be employed in supporting the seat one adjacent to each end of the seat.

The present invention is directed to the provision of animproved form of pedestal so constructed that great strength is secured in astructure which is of light weight and so formed that it may be manufactured at comparatively. low cost.

The improved pedestal possesses the further advantages that it is well adapted for use'as, a support for the aisle end of a carseat arranged adjacent to a trap door in the floor of a'car, in which case the pedestal must be set inwardly from the end of the seat a substantial distance.

The preferred embodiment of the inven-. tion is illustrated in the accompanying drawings in which 7 Figure 1" is an elevation of the pedestal, Fig. 2 is an end view of the pedestaLFig.

-3 is a top view of the pedestaland Fig. 4 is a ectional detail view on line H of Fig.1.

' Referring to these drawings, the pedestal consists, of a base 1, of hollow sheet-metal and closed at its upper end. This base is preferably pressed. into the form shown from av single piece of sheet-metal. It is of oval-cross-section throughout and has a flar- 1 ing bas'e terminating in a flange 2. The

closed upper end of the pedestal is shown at 3. 7

The two arms of the pedestal are-shown at and thes a m t nd g ar y and rear ardly from th upper end of the 'trated.

base 1 as shown in Fig. 3. The arms 4 and 5 are both arranged on one side of the general plane of the pedestal, that is, both arms are arranged on the same side of a plane passing through the major axis of they oval of the base. Each armis of inverted U-shape in cross-section, as best shown in Figs. 1 and 4, and the outer end of each arm is closed as shown at 10. Preferably each arm 4 and 5 is formed by pressing a piece of sheet-metal to the shape illus- After the two arms have been formed separately, as above indicated, they are secured together to form an integral structure as by welding their abutting edges together. The line of the welding is indicated by the dot and dash line on Figs. 1 and 3. The unitary structure constituting the two arms is then secured to the upper end of base 1 and this is also done by a process of Welding. In preparing the base 1 for securing the arms thereto, the metal of the base 1 is out along a horizontal line adjacent to the top 3 of the base as indicated by thereof along a horizontal line adjacent to the top 3 as indicated by the reference 7 on Fig. 2, this cut extending substantially half way around the top portion of the base, and having a slight depth below the top 3 as in dicated at 7 in the figure. These two cuts having been made, the metal ofv the base 1 is preferably pressed inwardly along lines extending vertically downward. from the ends of the .cut 7, as indicated at 8 on Fig. 3, these inwardly pressed portions extending downwardly fora suitable distance, say one inch, fromthe plane of the cut-away POI'". tion, or seat, 7. The base and the unitary structure including the two arms having been constructed thus and the outer side walls of the arms having downwardly extending edges 9 adjacent the portions which seat on the cut-away'part 7 of the base the two parts are assembled in the relation Steve. i he dra i g With he two ge Patented May 23, 1916. i

of the metal joining the two arms entering the cuts formed in the upper portion of the base 1 and the downwardly extending edges 9 of thenon-adjacent sidewalls of the two arms extending downwardly along the outer sides of the base 1 and lying in the depressions 8. The abutting surfaces of the two "pieces are then welded together. The weld-.

ing covers the surface of the portions 9 of the arms which overlie the depressions 8 p and also it extends along those edges of the arm-structure which enter the cuts forme in the'base along the lines 6 and 7;

It will be seen that joining'to'gether the inner and outer flanges of the arms in the manner described, that is, welding together the abutting edges of the inner flanges 4 and 5, and of the outer flanges 4: and'5 of the inverted U-shaped arms, forms an interrupted or partial base portion for the combined arms, of substantially the same cross-section as that of the pedestal base at i the top thereof.

When the parts have been assembled'together thus a structure-of great strength is provided and moreover, the structure is "of light weight.

g The arms ofthe pedestal are extended a substantial distance; to one side of the plane 'ofthe pedestalbut the joint between the arms and the base is of e. such character that there is little or no danger ofbreakage at thispoint; By reasonof the lateral extension of the arms l and'5,

the base of the pedestal maybe setina sub-' stantial distance from the'en'd'ofa car-seat while still supporting the seat structure at points substantially close to the aisle end of the seat. This pedestal may, therefore, be used in a car at a point where a trap door is providedfinthe floor of the car togive access to the underlying parts and permits of making the trap door of substantial size without having its removal obstructed by the pedestal.

' The seat-structure is secured upon the ends of thearms 4 and 5 in any suitable manner.
